Curve suggesting the relation of Parapavo (3) to the living Pavo (1) and Agriocharis (2). , In the character of its hypotarsus, Parapavo is more remote from Agriocharis than is Pavo, in the nature of the spur, it is intermed- iate but approaches closely to Agriocharis, in elevation of the spur it is again intermediate but closely approximates Pavo, etc. Values approximated only. are no differences between the birds as known by the tibiotarsus. Adult specimens of both sexes yield the following measurements: Table of Measurements of the Tibiotarsus P. cristatus M. oeellatus P. californicus Male Male Female Male Female Total length mm. 187. 170. 205. 172.

Femur.—Several points of difference are to be noted on comparing the femur in the living peacock and the ocellated turkey. Proportions are again reversed and Pavo is found to be the stouter. The stoutness may however be due to a greater degree of pneumaticity. Several. Please note that these images are extracted from scanned page images that may have been digitally en
